Слишком сложная ошибка PEP257, не знаете, как ее исправить.

Я получаю ошибку PEP257 с этой частью кода. Я знаю, что добавление более 3, если / elifs вызывает это, но я не уверен, как правильно это исправить.

Я пытался сгруппировать ifs / elifs, но это сделало его слишком сложным дляЯ и я не нашли других хороших решений от доктора Гугла. 

def determine_winner(name: str, user_choice: str, computer_choice: str, reverse_name: bool = False) -> str:
    """
    Determine the winner returns a string that has information about who won.

    You should use the functions that you wrote before. You should use check_user_choice function
    to validate the user choice and use normalize_user_name for representing a correct name. If the
    function parameter reverse is true, then you should also reverse the player name.
    NB! Use the previous functions that you have written!

Используйте тот факт, что return завершает выполнение. 

    user_choice = user_choice.lower()
    computer_choice = computer_choice.lower()

    if computer_choice not in {"rock", "paper", "scissors"}:
        return "There is a problem determining the winner."

    if reverse_name:
        name = reverse_user_name(name)

    choices = normalize_user_name(name) + " had " + user_choice + " and computer had " + computer_choice

    if user_choice == computer_choice:
        return choices + ", hence it is a draw."

    if user_choice == "rock":
        if computer_choice == "paper":
            return choices + ", hence computer wins."
        return choices + ", hence " + normalize_user_name(name) + " wins."

    if user_choice == "scissors":
        if computer_choice == "paper":
            return choices + ", hence " + normalize_user_name(name) + " wins."
        return choices + ", hence computer wins."

    if user_choice == "paper":
        if computer_choice == "scissors":
            return choices + ", hence computer wins."
        return choices + ", hence " + normalize_user_name(name) + " wins."

    return "There is a problem determining the winner."
